详解vue中axios的封装

cnpm install axios -S

import axios from 'axios';import { Message } from 'element-ui';axios.defaults.timeout = 5000;axios.defaults.baseURL ='';//http request 拦截器axios.interceptors.request.use( config => {  // const token = getCookie('名称');注意使用的时候需要引入cookie方法，推荐js-cookie  config.data = JSON.stringify(config.data);  config.headers = {   'Content-Type':'application/x-www-form-urlencoded'  }  // if(token){  //  config.params = {'token':token}  // }  return config; }, error => {  return Promise.reject(err); });//http response 拦截器axios.interceptors.response.use( response => {  if(response.data.errCode ==2){   router.push({    path:"/login",    querry:{redirect:router.currentRoute.fullPath}//从哪个页面跳转   })  }  return response; }, error => {  return Promise.reject(error) })/** * 封装get方法 * @param url * @param data * @returns {Promise} */export function fetch(url,params={}){ return new Promise((resolve,reject) => {  axios.get(url,{   params:params  })  .then(response => {   resolve(response.data);  })  .catch(err => {   reject(err)  }) })}/** * 封装post请求 * @param url * @param data * @returns {Promise} */ export function post(url,data = {}){  return new Promise((resolve,reject) => {   axios.post(url,data)     .then(response => {      resolve(response.data);     },err => {      reject(err)     })  }) } /** * 封装patch请求 * @param url * @param data * @returns {Promise} */export function patch(url,data = {}){ return new Promise((resolve,reject) => {  axios.patch(url,data)     .then(response => {      resolve(response.data);     },err => {      reject(err)     }) })} /** * 封装put请求 * @param url * @param data * @returns {Promise} */export function put(url,data = {}){ return new Promise((resolve,reject) => {  axios.put(url,data)     .then(response => {      resolve(response.data);     },err => {      reject(err)     }) })}

import axios from 'axios'import {post,fetch,patch,put} from './utils/http'//定义全局变量Vue.prototype.$post=post;Vue.prototype.$fetch=fetch;Vue.prototype.$patch=patch;Vue.prototype.$put=put;

mounted(){  this.$fetch('/api/v2/movie/top250')   .then((response) => {    console.log(response)   }) },其余的方法一样
